The app fetches the issue list and reactions from the github API and stores them in the browser local storage.
They then are rendered using react, and styled using the materializecss responsive framework.

The list of topics is updated automatically only if an issue changed using conditional HTTP requests. This way the rate limit for the anonymous usage of the github API is not reached.

It took 6 hours for the initial development and then another 6 hours of additional tweaks.
